IMPROVEMENT IN SAW-FRAMES.

Specification forming part of Letters Patent No. 164,449, dated June 15,1875; application filed May 21, 1875. I

To all whom it may concern:

Be it known that I,W1LLIAM HANKIN, of Seelyville, in the county of Wayneand State of Pennsylvania, have invented a certain new and usefulImprovement in Saw-Frames, of which the following is a full, clear, andexact description, reference being had to the annexed drawing and theletters of reference marked thereon, in which- Figurel is a sideelevation of my improved buck-saw, and Fig. 2 is a view thereof, partlyin section and elevation.

Corresponding parts in the two figures are denoted by like letters.

This invention relates to a certain improvement upon my Letters PatentNo. 129,731, granted July 23, 1872; and' it consists in thedetachability of the diagonal brace from the saw-frame, and the lookingof the same to the horizontal or middle bar of said frame, substantiallyas hereinafter more fully set forth.

To enable others skilled in the art to which my invention appertains tomake and use the same, I Will proceed to describe it.

In the annexed. drawing, A rei'ers to the saw-handle, and B to a similarbut shorter piece, the two constituting the side pieces of thesaw-frame, within which the saw-blade C is suitably secured. D is ahorizontal bar connecting the parts A and B together about midway oftheir lengths. Firmly secured within and projecting above the said bar Dobliquely to its longitudinal axis, as seen in Fig. 2, is a stud orstout piu, E, the function of which will appear hereinafter. F is adiagonal brace reduced or tapered at its ends, as are also those of thehorizontal bar D and entering mort-ises in the side pieces A and B. Therear end of the brace F is provided in its lower side with a socket, f,as shown in Fig. 2, to receive the projecting portion of the stud or pinE, by which it is locked to the bar D, the opposite ends of said braceand bar being secured, as shown in the drawing, to give them a firmjoint-bearing in the side piece B. The forward or opposite end of thebrace F is provided with a pivoted clip or bow, G, which receives andfits down over the handle or side piece A into a socket or recess, g,therein to detachably secure the said brace in place thereon.

By means of this combination and construction of parts the use of nuts,which, when rusted by the weather, become difficult to remove, &c., isdispensed with, the separation of the parts of the saw-flamefacilitated, simplicity and lightness of construction obtained, andconvenience in handling the saw prolnoted. The upper ends of the piecesA B may be united by a rope, H, twisted in the old way with an insertedpiece or stay, h, or otherwise, as desired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination of the brace F, having the pivoted bow or clip G, sidepieces A B, socket f, horizontal bar D, having the stud or pin E, andtwisted rope H and lever h, or their equivalents, when constructcd tooperate as and for the purpose set forth.

In-testimony whereof I have hereunto si gned my name in presence of twosubscribing witnesses.

WM. HANKIN.
